Oil change Problem

[ughmo2000]

Like Mary51, I also add a bit of fresh oil after initial draining, allowing that to drain as well. It may not help but I believe it does get the last of comtaminated oil from engines. Course if you really want your engine to last get a pre-oiler system!

According to directions..pump about 8 times, and the oil then is supposed to siphon..

I'm pumping like a madman.. "US pumping team candidate" it draws up maybe half way and won't go any further..Some one suggested..run the engine to heat the oil...brought it up to 175..helped a bit bit no cigar..10-40 oil

I'm down in Mexico where resources of other apparatus is limited to none...gotta get this to work..any suggestions..

This is a 50 hr oil change on a new Yanmar 4HE Engine...First experience changing the oil...used this on a friends boat..on a Volvo worked just fine..

Hi,I'm Capt Thor,I hope I can help you with this problem,I have had similar in middle of nowhere> First of all,look at the end of pipe that goes down the dipstick hole,it is too be cut in an angle that steep,it never sucks to the bottom of the pan.Then next look for leaks on the container most likely by the pump.If you can get the plunger out of the pump cylinder inspect the o-ring or what ever it is tightened with.Might even be skin from leather,that can be renewed from pair of gloves>
Let me know how this winds on
All the best Capt Thor

Thanks for your help..I lucked out...One of he guys at the Marina had a Tempo as pictured..."the dirty deed done."..Need to be careful..He gave it to me..and right away I noticed the hose too bg to fit down to end of dip stick level...I took the extension off my cheap apparatus and over the Tempo hose...the Tempo worked fine..extracted 5 quarts through vacuum pressure..

Lesson to be learned don't waste your 35 bucks on the cheap West Marine model...doesn't have enough vacuum pressure for my Yanmar
